Notes:

1.You can extend the serial/power wiring of the GSD 21 power/data cable up to 100 ft (30 m) total length. Use the CANet Extension Cable or 22 AWG, 4-conductor shielded cable for data connections and 18 AWG for power.

2.Ground the drain wire at the display unit. Do not ground the drain wire on the sonar unit.

3.Refer to the chartplotter’s specific Installation Instructions for wiring the GPS 17 sensor and other devices.

4.When crimping the 3-wire connector, use a standard pair of pliers and make sure the button is fully depressed into the connector.
